peaking

Incorrect forming of the plate edges into the pipe curvature during fabrication, resulting in meeting of the edges as a triangular apex with the seam weldThe longitudinal or helical (also referred to as spiral) weld in pipe that was formed by joining two pieces of metal along their edges or seams. projecting beyond the circular contour of the pipe, also called peakingIncorrect forming of the plate edges into the pipe curvature during fabrication, resulting in meeting of the edges as a triangular apex with the seam weld proje… or angular misalignment.
